I was browsing some local news blogs and came across these newspaper scans from the 1950s. They seem to detail community proposals for what are now I-95, I-64, and their overlap through central and eastern Richmond. Unfortunately, there's not a whole lot in the way of text. Basically, it proposes a freeway to run about 1/2 to 1 mile south of where current I-64 is just east of I-95, and a north-south freeway in central Richmond with an interchange at Franklin Street (and oddly enough not Main, which was/is VA 147 in that location - and yes, I know I-95 blows off VA 147 today).

Interestingly it should be noted that the proposed routing of I-64 would have destroyed a good chunk of Church Hill and Fairmount, and the apparent proposed I-95 (I'm guessing it's I-95, as it's a north-south freeway; the drawing is looking south) was a depressed freeway unlike current I-95 south of I-64. Not sure that would have worked either without destroying Shockoe Bottom.
